Adjustable weight golf club head

Abstract

A golf club head, and particularly a putter head, having a generally horizontally disposed weight receiving cavity which extends longitudinally and laterally within the club head, and one or more weight members having weight securing means to releasably attach the weight members within the weight receiving cavity at any position laterally or longitudinally within the weight receiving cavity.

We claim: 
     
       1. A golf club head having a striking face, a toe end, a heel end, a rear wall, a sole and a top surface, further comprising a generally horizontally disposed weight receiving cavity extending laterally through said club head from an access opening in said rear wall toward said striking face and extending longitudinally through said club head the majority of the distance between said toe end and said heel end, said weight receiving cavity having a generally parallel upper surface and lower surface, and further comprising at least one weight member fitting within said weight receiving cavity, and weight member securing means to releasably secure said at least one weight member at a fixed position contacting said upper and lower surfaces within said weight receiving cavity, where said at least one member is comprised of a first weight component and a second weight component connected to each other by said weight member securing means, and where said first weight component has a non-threaded bore and said second weight component has a threaded bore, and where at least one of said first and second weight components has a bevelled contact wall, and where said weight securing means comprises a threaded bolt member inserted through said non-threaded bore and said threaded bore, whereby tightening said threaded bolt member causes said at least one weight member to be wedged against said upper and lower surfaces of said weight receiving cavity. 
     
     
       2. The golf club head of claim 1, where said at least one weight member is positionable at different positions within said weight receiving cavity at any position both laterally in the direction from said striking face to said rear wall and longitudinally in the direction from said toe end to said heel end in order to alter the weight distribution of said golf club head. 
     
     
       3. A golf club head having a striking face, a toe end, a heel end, a rear wall, a sole and a top surface, further comprising a generally horizontally disposed weight receiving cavity extending laterally through said club head from an access opening in said rear wall toward said striking face and extending longitudinally through said club head the majority of the distance between said toe end and said heel end, and further comprising at least one weight member fitting within said weight receiving cavity, and weight member securing means to releasably secure said at least one weight member at different positions within said weight receiving cavity at any position laterally and longitudinally within said weight receiving cavity in order to alter the weight distribution of said golf club head. 
     
     
       4. The golf club head of claim 3, where said at least one member is comprised of a first weight component and a second weight component connected to abut each other by said weight member securing means. 
     
     
       5. The golf club head of claim 4, where said first weight component has a non-threaded bore and said second weight component has a threaded bore, and where at least one of said first and second weight components has a bevelled contact wall, and where said weight securing means comprises a threaded bolt member inserted through said non-threaded bore and said threaded bore, whereby tightening said threaded bolt member causes said at least one weight member to be wedged against said upper and lower surfaces of said weight receiving cavity. 
     
     
       6. The golf club head of claim 3, said weight receiving cavity having a generally parallel upper surface and lower surface, where said weight member securing means releasably secures said at least one weight member at a fixed position contacting only said upper and lower surfaces within said weight receiving cavity.
